I am getting following error when running maintenance plan under schedule job. I am getting this error for maintenance cleanup task. ÃÂ The job is not failing all the time but alternate weeks. I created same maintenance plan on test server(same configuration as PROD) and Maintenance cleanup task related job failed for first time and running fine from there. I don't know why it is causing failed. I checked maintenance plan history and it show successful each time. even i checked manually it deleted all the report files related toÃÂ maintenanceÃÂ plan. History Cleanup task and Maintenance Cleanup task should not be created on same Maintenance Plan?....I know SQL Server 2005 had some problem with maintenance plan creation before SP2.
